Sapphire has used the standard Award Modular BIOS version 6 that we have become quite accustomed to. Overclocking options for the CPU and memory are located under the power user overclock settings menu; however, a few extra settings are hidden under the Advanced Chipset Features menu.
The 790GX chipset has its own onboard graphics processor thanks to ATI's HD Radeon 3300 series. The clock of the GPU is set for a base clock of 700MHz; however, Sapphire gives you the option to overclock the onboard IGP up to 900MHz in 1MHz increments. The disappointing part of this is that the board comes with 128MB of 400MHz GDDR3 memory for its frame buffer and unfortunately you can't overclock this.
Lastly, under the Power User Overclock setting menu there are all the major tweaks like FSB clock, PCIe clocks, memory clocks, ratios, dividers and voltage.Overclocking
Overclocking on this board wasn't as impressive as we may have thought. With all the tweaks and such we didn't get past 220MHz FSB; however, this did get our CPU up quite a bit nonetheless.Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
